Dairy Queen will offer free gift cards to the first 50 customers on the opening day of its new Union Square location on May 29, 2014. To celebrate the launch of the national chain’s first Manhattan location at 54 W. 14th St., the store will hand out free gift cards to the first 50 customers and free T-shirts to the first 200 customers. The gift cards that the first 50 customers receive will allow them to get one free Blizzard — a thick soft-serve treat with candy, fruit and other toppings mixed in — each month for the next year. The Union Square Dairy Queen will be open from 10 a.m. to midnight Monday through Thursday and 10 to 1 a.m. Friday through Sunday. LINK
